AW: PowerPC PCI DMA issues (prefetch/coherency?)

From: <hidden>
Date: 2009-06-22 14:56:29
Also in: lkml

The other part of the fix is in asm-powerpc/pgtable32.h. _PAGE_BASE
needs _PAGE_COHERENT in order to work correctly, and in fact there is
now a comment in there to that affect in 2.6.29. Backporting that change
has made it work on 2.6.26. Both this patch, and the fix to head_32.S
are needed for it to work correctly on older kernels.

Hello Chris,

sorry for dummy, but if it possible, could you, please, send a correspondin=
g summary patch of backporting you've done for older kernels?
or just summary of that changes once again?

Many thanks
